3. Using the method of mechanical dispersion of 5 g of toluene in 1 liter of water, a disperse system with spherical toluene particles with a radius of 2.5 * 10-7 m was obtained. The density of toluene is 0.867 g/cm3.
1) Calculate the dispersion of the system and the specific surface Sul.
2) Determine the type of system based on all classification criteria.
3) Calculate the parameters of a toluene particle: volume Vo, surface S0, mass m0.
